Delta manganese dioxide nanosheets decorated magnesium wire for the degradation of methyl orange.

MnO-decorated magnesium wire composite (MnO-M) was fabricated via a simple hydrothermal reaction and accompanied by the calcination process (MnO/MnO-M). To clarify the optimized reaction condition of δ-MnO in the system, the effect of different pH, temperature and pollutant concentration of methyl orange (MO) for degradation process were investigated. Experimental results showed that MnO-M achieves a high removal rate of 76% (2h, at 25°C) in the presence of HO at pH 2.
